NAS InSight Mars Crust Interior
NASA’s InSight spacecraft may have landed on Mars in 2018, but the rovers and orbiters studying the Red Planet concentrated on its surface still provide valuable data today. More specifically, the stationary lander’s seismometer, which gives us the first details on the depth and composition of Mars’ crust, mantle, as well as core, including confirmation that the planet’s center is molten. Read more for two videos and additional information.

InSight’s seismometer is officially called the Seismic Experiment for Interior Structure (SEIS) and has thus far recorded 733 distinct marsquakes. Approximately 35 of those, ranging between magnitudes 3.0 and 4.0, provided the data for the three papers since it enables scientists to “hear” seismic events from hundreds to thousands of miles away.

Celestron - NexStar 127SLT Computerized Telescope - Compact and Portable - Maksutov-Cassegrain Optical Design - SkyAlign Technology - Computerized Hand Control - 127mm Aperture
  • Computerized star locating telescope: The Celestron NexStar 127SLT is a computerized telescope that offers a database of more than 40,000 stars, galaxies, nebulae, and more. The telescope locates your object with pinpoint accuracy and tracks it.
  • Compact and portable: This telescope for adults and kids to be used together is ideal for weekend camping trips or excursions to dark sky sites. Its compact form factor makes it easy to transport and assemble just about anywhere.Optical Tube:Aluminum
  • Maksutov-cassegrain optical design: The NexStar 127SLT is the second-largest in the SLT family. The 127mm aperture gathers enough light to see our Solar System and beyond. View Saturn’s rings, Jupiter’s cloud bands, and the Moon in brilliant detail.
  • Fast setup with skyalign: Celestron’s proprietary SkyAlign procedure has you ready to observe in minutes. Simply center any 3 bright objects in the eyepiece and the NexStar SLT aligns to the night sky, ready to locate thousands of objects.
  • Bonus free starry night software: The NexStar 127SLT Computerized Telescope includes a free download of one of the top consumer rated astronomy software programs for an interactive sky simulation.

When we first started putting together the concept of the mission more than a decade ago, the information in these papers is what we hoped to get at the end. This represents the culmination of all the work and worry over the past decade,” said Bruce Banerdt, InSight’s principal investigator of NASA’s Jet Propulsion Laboratory in Southern California.
